Add a check in `ReflectionCapabilities#interfaces` which determines if
the passed-in type implements a Lifecycle Interface but does not declare
that it does so.
See https://goo.gl/b07Kii for details.
Closes#6849
BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
BREAKING CHANGE:
In Dart we used to support injecting types with generics. As this feature is hard to implement with the upcoming codegen we are dropping it.
Merge cl/115454020 in G3 with this change.
Closes#7262
This resolves Duplicate Identifier issues seen by many users,
at the expense of more typings installation required in some
cases.
Removes the quickstart hack of placing all needed dependencies
typings files in our distribution. Removes dependencies on
nodejs from angular2/core.
Fixes#5973Fixes#5807Fixes#6266
Angular now depends on es6-promise and es6-collections
(and a handful of manual typings) rather than all of es6-shim.
Fixes#5242
We previously had an undocumented breaking change, this is now
documented in this commit.
Fixes#6817
BREAKING CHANGE:
Transitive typings are no longer included in the distribution.
You may need to install typings in your project using
http://github.com/typings/typings
Users now must rely on getting typings from:
- one of the peerDependencies, such as rxjs, which exposes
typings via the moduleResolution=node mechanism.
(see https://github.com/Microsoft/TypeScript/wiki/Typings-for-npm-packages)
This happens automatically.
- Using --target ES5 now requires manual installation of
es6-promise and es6-collections typings.
- Using some angular APIs may introduce a dependency on eg. nodejs
or jasmine, and those typings need manual installation as well.
Closes#6267
Now, using `ng.probe(element)` in the browser console returns
a DebugElement when in dev mode.
`ComponentFixture#debugElement` also returns a new DebugElement.
Breaking Change:
This is a breaking change for unit tests. The API for the DebugElement
has changed. Now, there is a DebugElement or DebugNode for every node
in the DOM, not only nodes with an ElementRef. `componentViewChildren` is
removed, and `childNodes` is a list of ElementNodes corresponding to every
child in the DOM. `query` no longer takes a scope parameter, since
the entire rendered DOM is included in the `childNodes`.
Before:
```
componentFixture.debugElement.componentViewChildren[0];
```
After
```
// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];
```
Before:
```
debugElement.query(By.css('div'), Scope.all());
```
After:
```
debugElement.query(By.css('div'));
```
Before:
```
componentFixture.debugElement.elementRef;
```
After:
```
componentFixture.elementRef;
```
BEFORE:
The following would throw in the dev mode because `f` would return a new array when called by checkNoChanges.
@Component({
template: `
{{f()}}
`
})
class A {
f() { return [1]; }
}
AFTER:
The checkNoChanges function compares only primitives types for equality, and deeply compares iterables. Other objects cannot cause checkNoChanges to throw. This means that the dev mode would never fail given a legal program, but may allow some illegal programs.
This is needed to prevent memory leaks. The DOM
listeners don’t need to be removed for simple examples,
but a big internal app shows memory leaks because of them.
BREAKING CHANGE:
- `Renderer.listen` now has to return a function that
removes the event listener.
Resolve all invalid field override errors, workaround current
reflection limitations in Dart Dev Compiler. todo, hello_world and
key_events samples now work with Dart Dev Compiler.
BREAKING CHANGE: remove TemplateRef.elementRef setter
